Be my Valentine – Interesting facts about animal hearts
With Valentine’s Day approaching, and gaily colored hearts everywhere, we can’t help but think of love. And who gives us more unconditional love than our animal friends?
Here are some fun heart and love-related animal facts:
- A hummingbird’s heart rate can soar up to 1000 beats per minute in some species
- A blue whale’s heart is as big as a compact car.
- Whooping cranes do an impressive mating dance that seems to work well, since these birds mate for life
- Octopuses have three hearts.
- Although coronary artery disease is common in people, it is very rare in cats and dogs.
- Zebrafish can regenerate their hearts.
- A seal’s heart rate can go as low as 10 beats per minute during an extended underwater dive.
- Mammals have four chambered hearts, but many reptiles have hearts with only three chambers. Fish only have a two chambered heart!
- Giraffes have the highest blood pressure of any mammal, measuring 280/180
Since funding its first heart disease study in 1960, Morris Animal Foundation continues investing in the best animal science focused on heart related issues, including our latest initiative looking at the inherited causes of heart disease in small breed dogs. Together, we hope to celebrate many more Valentine’s Days with our pets.
